Hello to everyone and thanks for inviting me to this group! I was

asked to introduce myself so I’ll give you a description of myself:

I am 33 years old and live near the city Graz in Austria. Currently

I’m working as a software-engineer, developing software in the field

of cryptography/digital signatures/pki. My first contact with the

original Rubiks cube was at the age of twelve, back in 1982. I was

able to solve the cube using some layer method that I didn’t invent

myself. About one year ago I ran across Mefferts website and decided

to try to find my own solution to all those puzzles that are

available there. So time by time I bought the 2x2x2, 3x3x3, 4x4x4,

5x5x5 cube, the pyraminx, the megaminx, the square one, the skweb and

a few others and solved them, beginning with the easier ones and

progressing to the harder ones. Luckily I had forgotten most of the

moves I had learned by heart 20 years ago for the 3x3x3, and for

those that I remembered I found other moves with the same effect, so

I can honestly say that I did it on my own. After solving the 5x5x5,

which in fact wasn’t really a new challenge after the 4x4x4, I found

the Magic 4D Cube website and tried the 4th dimension. It took me

quite a few hours to understand how everything was moving, but after

that I found that I could use the same principles I used for the 3D

cubes. I didn’t look at the solution at the website to solve the

cube, but searched for my own operators, which were not very

difficult to find. I used my operators for the following operations

(using the names from the website solution:

1) Exchanging 3 faces

2) Rotating 2 faces

3) Exchanging 3 edges

4) Rotating 2 edges

5) Exchanging 3 corners

6) Rotating 2 corners

So exchange always takes place as a cycle of three, rotating is

always done with two pieces, where one is rotated inversely to the

other. I first did all the faces, then the edges and at last the

corners. After positioning a piece I immediatly rotated it if the

orientation was wrong. I know, it would have been a little more

efficient to care for the orientation later, after positioning all

pieces of the same kind, but it was easier this way. You can very

easily get lost!

I was proud of finishing the 4D-Cube, but was really surprised to

read that only 14 other people had done this before! But I think this

may be partly due to the fact that not many people are aware of this

website. Anyway, it isn’t an extremly difficult task, it’s rather a

very tedious one.

And thanks again to the people who created the software and made it

available for everybody!

Regards

Wolfgang Würfel
